football at zona esportiva (just as you come into tossa by the roundabout with the flags and the fountain.) they also do swimming and other sportie stuff.

tennis is at the hotel marina tossa (ex le heaux), 2 courts and a free car park next door, and is a little more down the road to the town centre. and also at platja del reig, (on the sea front) and camping pola, cala giverola.

the two campsites on the way in to town also show various sports stuff.
hope this helps.
